EXECUTIVE SUMMARY Fish passage impediments created by road crossing structures in British Columbia are a significant challenge that can have a substantial cumulative impact on local fish populations by reducing access to critical habitat and fragmenting populations. Closed bottom road crossing structures (culverts) can present barriers to fish migration due to a number of factors including increased water velocity, turbulence, a vertical drop at the culvert outlet and/or maintenance issues. The rehabilitation of fish passage at road crossing structure barriers presents tangible opportunities to reconnect habitat values within currently fragmented ecosystems.

The Bridge-Seton River watersheds was chosen for assessment planning due to a synergy between the objectives of the British Columbia Ministry of Environment and Climate Change Strategy- Ecosystem Branch and the Fish and Wildlife Compensation Program (FWCP) – Coast Region objectives. An organized approach to fish passage remediation in the watershed takes action towards implementation of some of the high level objectives of both organizations which are included in the Bridge-Seton Rivers Watershed Action Plan:

• the conservation and restoration of habitat capacity and diversity for fish and other aquatic organisms • to sustain and increase the population viability of anadromous salmon (coho, chinook and sockeye) and steelhead as well as resident salmonids (bull trout, rainbow and kokanee). • Maintain or improve opportunities to sustainably use ecosystem values for sustenance, social, ceremonial, recreational and commercial purposes.

Previously identified crossings that are barriers to fish passage in the Bridge-Seton watersheds were prioritized based on past assessment information, available fisheries data as well as estimated upstream habitat quality and quantity. The results provide a planning tool to help guide further assessment and restoration of crossings.

A detailed review and prioritization ranking was conducted for 15 crossings structures identified as requiring further assessment according to the criteria identified in the methodology. Of these, 10 crossings were rated as high priority for follow up with habitat confirmation assessments and potentially fish inventories. Four crossings were rated as moderate priority for follow up with habitat confirmation assessments and potentially fish inventories and one crossing was rated as low priority for follow up with habitat confirmation assessments and potentially fish inventories. Of note, site plans have already been drafted for rehabilitation of three of the crossings rated as high priority so further ground surveys may not be required at these locations.

To date fish passage assessments appear to have been conducted throughout most of the major potential fish bearing areas of the Bridge River watershed. However a substantial number of modelled crossings do not have associated inventory data. Fish passage culvert inspections were conducted in the

Bridge Creek watershed for Ainsworth Lumber Company Ltd. in 1999, although this data does not appear to be accessible within the Provincial Stream Crossing Inventory System (PSCIS) database. Ainsworth Lumber may have the digital record for the surveys which could prove useful for planning and coordination of future fish passage assessment in the watershed. Currently there is no data from stream crossing inventories in the Seton River watershed located within the PSCIS database.

Within the Bridge River watershed 668 of the crossings not associated with PSCIS crossings are modelled as on observed or potentially fish bearing habitat. Within the Seton River watershed 271 crossings are modelled as on observed or potentially fish bearing habitat. Forsite (2008), reports that some modelled crossings located on Cadwallader Creek and north of Liza Lake upstream of barriers should not be inventoried as these areas are non-fish bearing.

Assessment of crossing locations in the Bridge and Seton Rivers watersheds on modelled fish habitat that do not have associated PSCIS data is recommended and should be conducted according to Fish Passage Technical Working Group (FPTWG) protocols. The FPTWG has prepared on-line training resources, field work guidance, field assessment protocols and data forms to help guide the collection of data and submission of assessment deliverables.

Habitat confirmation checks conducted according to protocols developed by the FPTWG are recommended for the crossings rated as high priority for follow up. Habitat confirmation checks gather detailed field and background data on habitat quality and quantity, fisheries values, land use issues and regional fisheries concerns. This information is then incorporated into a standardized reporting format to further refine priority rankings and focus design (Phase 3) and remediation (Phase 4) on fish passage restoration opportunities into areas of critical habitat for species of interest.

1 INTRODUCTION The health and viability of freshwater fish populations depends on access to suitable spawning, high water refuge, rearing and overwintering habitat. Watershed connectivity is important to accommodate population abundance fluctuations and the flow of genes that provides resilience to environmental stressors such as floods, landslides and extreme climate events.

Fish passage impediments created by road crossing structures in British Columbia are a significant challenge that can have a substantial cumulative impact on local fish populations by reducing access to critical habitat and fragmenting populations. Estimates based on fish passage data collected to date indicate that there are over 170,000 closed bottom culverts in the province that impede fish passage (FPTWG 2014). Closed bottom road crossing structures (culverts) can present barriers to fish migration due to increased water velocity, turbulence, a vertical drop at the culvert outlet and/or maintenance issues. Rehabilitation and replacement of crossing structure barriers can provide access to currently isolated high value habitats.

For this project, existing fish passage information in the Bridge-Seton Rivers watersheds, near Lillooet, British Columbia, was reviewed in order to prioritize and rank culverts for follow up in preparation for further assessment and restoration. A literature and Provincial Steam Crossing Inventory System (PSCIS) database review was conducted and rehabilitation opportunities were analyzed within the context of a GIS generated Fish Habitat Model of the known or potential fish habitat located upstream.

2 BACKGROUND As a result of high-level direction from the provincial government, a Fish Passage Strategic Approach protocol has been developed for British Columbia to ensure that the greatest opportunities for restoration of fish passage are pursued. A Fish Passage Technical Working Group has been formed to coordinate the protocol and data is continuously amalgamated within PSCIS. The strategic approach protocol involves a four phase process as described in (FPTWG 2011): • Phase 1: Fish Passage Assessment – Fish stream crossings within watersheds with high fish values are assessed to determine barrier status of structures and document a general assessment of adjacent habitat quality and quantity. • Phase 2: Habitat Confirmation – Assessments of crossings prioritized for follow up in Phase 1 studies are conducted to confirm quality and quantity of habitat upstream and down as well as to scope for other potential nearby barriers that could affect the practicality of remediation. • Phase 3: Design – Site plans and designs are drawn for priority crossings where high value fish habitat has been confirmed. • Phase 4: Remediation – Implementation of reconnection of isolated habitats through replacement, rehabilitation or removal of prioritized crossing structure barriers.

The scope of this project includes portions of the planning for the first two phases of fish passage assessment in the Bridge-Seton Rivers watershed. The Bridge-Seton Rivers watersheds were chosen for assessment planning due to a synergy between the objectives of the British Columbia Ministry of Environment and Climate Change Strategy- Ecosystem Branch and the Fish and Wildlife Compensation Program (FWCP) – Coast Region objectives. An organized approach to fish passage remediation in the watershed takes action towards implementation of some of the high level objectives of both organizations which are included in the Bridge-Seton Rivers watersheds Action Plan (FWCP 2017):

To date, within the Bridge/Seton River watershed, 72 fish passage assessments (Phase 1) conducted at crossing structures are documented in the PSCIS database. The assessments were completed using standardized protocols (MoE 2009, MoE 2011). The Fish and Wildlife Compensation Program and the Ecosystem Branch of the Ministry of Environment & Climate Change Strategy have funded the review of existing PSCIS information and other background literature to prioritize and rank crossing rehabilitation opportunities in select watersheds for follow up with habitat confirmation assessments. Of note, site plans have been drafted for rehabilitation of PSCIS crossings 531, 540 and 196501 over Quartz Creek with details provided within the PSICS database.

3 OBJECTIVES Objectives for the project include: 1. To review existing fish passage information in the Bridge-Seton Rivers watersheds in order to prioritize and rank crossing rehabilitation opportunities for follow up with habitat confirmation assessments. 2. Provide some of the background and field work tools necessary to facilitate an inventory of unassessed stream crossing structures on fish bearing and potentially fish bearing streams in the Bridge-Seton Rivers watersheds according to the FPTWG standards (MoE 2011).

It is important that future data collected be loaded into the PSCIS database so that the work will not be unnecessarily repeated and so that further phases of the Fish Passage Strategic Approach protocol can be prioritized towards crossings providing the best opportunities for rehabilitation.

4 STUDY AREA The Seton and Bridge rivers are located approximately 200km north-east of Vancouver near Lillooet, BC. The watersheds are within the traditional territory of the St’át’imc Nation. There are First Nation reserves in the lower Bridge River system and throughout the Seton River watershed. Protected areas within the watersheds include Duffy Lake Park, Nlhaxten/Cerise Creek Conservancy, and Spruce Lake. Industrial activity in the watersheds is predominately forestry, with historic and active mineral exploration also present. Crown land is extensive in the watersheds and supports recreation activities such as heli-skiing, snowmobiling, mountain biking, hiking fishing and hunting. The watersheds are located within the Cascades Natural Resource District (FWCP 2017)

The two watersheds are located in a rain shadow of the southern Coast Mountains (Figure 1). Elevation of peaks located on the west side of the watersheds are up to 3000 m, while the mouths of the rivers are located at approximately 250 m. Flows in the watershed are heavily influenced by snowmelt of a large snowpack and occurs primarily between May and September (Figures 2 – 3). The Bridge Glacier is located at the headwaters of the Bridge River and covers an area of approximately 140 km2 (FWCP 2017).

The Bridge River hydroelectric complex consists of La Joie Dam which impounds the river, forming the Downton Lake Reservoir. Water from La Joie Dam flows through the Middle Bridge River and into Carpenter Lake Reservoir. Terzaghi Dam stores water within the Carpenter Reservoir. Water is diverted from the reservoir into tunnels and penstock to the shore of Seton Lake.

The Seton Dam impounds Seton Lake which receives flows from the upper Seton River, Carpenter Reservoir and a diversion from Cayoosh Creek. Water from Seton Lake is diverted through a 3.7 km long power canal to the Seton Generating Station, which discharges directly to the Fraser River. Other releases of water from Seton Lake are diverted through release structures at the Seton Dam and flow to the Fraser River upstream of the Seton Generating Station and downstream of the confluence of the Bridge River. As part of the system, flows from Cayoosh Creek are diverted into Seton Lake from an independent power plant (Walden North). Flows above the operating capacity of Walden North are returned back into Cayoosh Creek which joins the Seton River approximately 500 m downstream of Seton Dam (FWCP 2017).

4.1 Fisheries Numerous fish species are reported as present within the Bridge River watershed in the provincial Fisheries Information summary system (FISS 2018, Table 1). When the Terzaghi Dam was first completed, there were no continuous releases into the lower Bridge River from the Carpenter Lake Reservoir. The lower Bridge River was essentially completely dry for a distance of 4 km and the remaining 15 km had extremely low water levels with inflows originating only from tributaries, groundwater and occasional releases due to high flows upstream. This altered flow regime caused profound impacts on anadromous and resident species in the watershed including changes in habitat quality and quantity. Currently flows are released from Terzaghi Dam to maintain riparian and aquatic habitat in this section of river (FWCP 2017).

Historically, anadromous salmon and steelhead (Oncorhynchus mykiss) likely had access to the Bridge River as far as La Joie and Zoltique Falls near the current site of La Joie Dam. As the lower Bridge River was dominated by high velocity flows through canyon habitat, much of the spawning and rearing habitat use by anadromous species was historically contained within the middle Bridge River and tributaries. Strong swimming species such as chinook (O. tshawytscha), coho (O. kisutch) and steelhead comprised substantial annual runs of spawners in this area. Sockeye salmon (O. nerka) runs were also reported as present in the middle Bridge River to a lesser extent. Pink salmon (O.gorbuscha) currently utilize the lower Bridge River where flows controlled by Terzaghi Dam are conducive for rearing and spawning. Numerous resident fish species are reported within the Bridge watersheds including bull trout (Salvelinus confluentus), rainbow trout (O. mykiss), mountain whitefish (Prosopium williamsoni), pacific lamprey (Lampetra tridentate), sculpin (Cottus spp.) and sucker (Catostomus spp.) (Table 1). Bull trout are considered vulnerable (blue listed) within British Columbia (FISS 2018, FWCP 2017, MoE 2018).

Numerous fish species are reported as present within the Seton River watershed in the provincial Fisheries Information summary system (FISS 2018, Table 2). Within the Seton River system there are anadromous runs of steelhead as well as sockeye, pink, chinook and coho salmon. Seton and Anderson Lakes function as nursery lakes for sockeye salmon and, historically, the watershed was a substantial producer of sockeye salmon. Known spawning areas for all salmonids in the watershed include Gates, Portage and the lower Seton River. Gates Creek is noted as the most important salmon stream in the watershed and supports populations of sockeye, coho and pink salmon. Numerous resident fish species are reported within the Seton River watershed including bull trout, rainbow trout, mountain whitefish, pacific lamprey, sculpin and sucker (Table 2, FWCP 2017, FISS 2018).

Fish passage culvert inspections were conducted in the Bridge Creek watershed for Ainsworth Lumber Company Ltd. in 1999; however, this data does not appear to be accessible within the PSCIS database (Inland 2000). Forsite (2008) conducted fish passage assessments in the Bridge River watershed in 2007 and all data was uploaded into the PSCIS database.

Bioterra (1998) conducted an overview fish habitat assessment for the Bridge Creek watershed. The report describes habitats as well as a number of barriers to fish passage and limits to upstream migration

Masse Environmental Consultants Ltd. 8 Analysis and Priority Identification for Fish Existing Passage Data - Bridge-Seton Rivers Watershed on the mainstem and select tributary streams such as Little Bridge Creek, O’Neil Creek, Donald Creek and Judson Creek. Fish inventory work has been conducted in the Bridge Creek watershed with information regarding fish distribution and the location of barriers (ARC 2001).

Although one fish passage assessment is detailed for the Seton River watershed within the PSCIS database there is no link to the project report and it appears as though the site location is out of place and likely from another watershed. There is a large amount of FISS sample sites within the Seton River watershed; however, no inventory and fish and fish habitat assessments could be located within government report repositories.

5 METHODS To identify priorities for crossing structure rehabilitation, a literature and PSCIS database review was conducted for the Bridge-Seton Rivers watersheds and data was analyzed within the Fish Habitat Model developed by Hillcrest Geographics and the BC Ministry of Environment (MoE 2016). The Fish Habitat Model identifies potential stream crossing locations and models known and potential fish habitat based on gradient. Gradient is calculated at intervals along a stream of at least 100 m to delineate segments based on a set of user provided gradient thresholds (MoE 2016). Following segment delineation, the average gradient of each segment is calculated and used to symbolize potential fish habitat as riffle/cascade, step-pool, step-pool very steep according to a set of average stream slope categories (0- 5%, 6- 13% and 13 – 20%).

Past fish passage assessment reports for the Bridge River watershed was first reviewed to identify crossing structure barriers previously ranked as high or moderate priorities for rehabilitation. All previously prioritized crossings underwent a detailed review. To identify previously un-prioritized crossing structure barriers located on potentially high value streams, road crossing structures that met the following criteria in the Fish Habitat Model and/or PSCIS database also underwent a detailed review. • Stream crossing barriers and potential barriers on streams with confirmed fish presence upstream of the structure. • Stream crossing barriers and potential barriers on streams documented as ≥ 1.5m wide with linear lengths of modelled upstream habitat <20% gradient for ≥100 m. • Stream crossing barriers and potential barriers located on streams classified as 3rd order or higher. • Stream crossing barriers and potential barriers located on streams with >1 ha of modelled wetland and/or lake habitat upstream of the structure. • Stream crossing barriers and potential barriers on streams with habitat value rated as “high” in past fish passage assessment data. Habitat value ratings are assigned during fish passage assessments and are defined in the Field Assessment for Determining Fish Passage Status of Closed Bottom Structures (MoE 2011, Table 3).

Masse Environmental Consultants Ltd. 9 Analysis and Priority Identification for Fish Existing Passage Data - Bridge-Seton Rivers Watershed

Table 3. Habitat Value Criteria. Habitat Value Fish Habitat Criteria High • The presence of high value spawning or rearing habitat (e.g., locations with abundance of suitably sized gravels, deep pools, undercut banks, or stable debris), which are critical to the fish population. Medium • Important migration corridor. • Presence of suitable spawning habitat. • Habitat with moderate rearing potential for the fish species present. Low • The absence of suitable spawning habitat, and habitat with low rearing potential (e.g., locations without deep pools, undercut banks, or stable debris, and with little or no suitably sized spawning gravels for the fish species present). Adapted from: MoE 2011

Crossing structures that underwent the detailed review were ranked for further assessment as either high priority, medium priority, low priority, or “no fix”, based on past assessment information, available fisheries data as well as upstream potential habitat quantity and quality. A combination of some or all of the following information was incorporated into this prioritization ranking: • Contractor crossing prioritization in past fish passage assessment reports and data. • Available fisheries data - Fish species present or suspected at the crossing location. • Habitat quantity: o Stream width as documented in the PSCIS database as well as at nearby sample sites documented within the Fisheries Information Summary System (FISS). o Linear length of modelled upstream potential habitat (<20%). Consideration was given to the “net” amount of habitat available upstream which is defined as habitat upstream of the crossing uninterrupted by subsequent barrier road crossing structures. o Area of modelled wetland and/or lake habitat upstream of the structure connected to crossing location by contiguous modelled gradients <20%. • Habitat quality: o Past crossing assessment and nearby FISS stream sample site comments regarding habitat quality, slope information in PSCIS/FISS databases and project reports as well as apparent habitat quality in site photos. o Modelled threshold gradient and average gradient outputs of upstream potential habitat generated by the Fish Habitat Model were also reviewed which is discussed in more detail below.

Gradient is a key factor in fish distribution and channel type. High value rearing, overwintering and spawning habitat is often located within channel types with lower gradients, while high gradient sections typically present upstream migration barriers and less available habitat. For this reason, waterbody segments in the Bridge-Seton Rivers watersheds were delineated and categorized into gradient categories using the Fish Habitat Model. The model outputs were used to identify potential gradient barriers as well

Masse Environmental Consultants Ltd. 10 Analysis and Priority Identification for Fish Existing Passage Data - Bridge-Seton Rivers Watershed as to help prioritize rehabilitation opportunities by estimating the slope and quantity of potential fish habitat upstream of a crossing.

The Fish Habitat Model utilized stream segments from the GIS stream layer (1:20,000) of the Freshwater Atlas for its gradient analysis (MoE 2016). For this project, the gradient categories detailed in Table 4 were utilized to delineate and classify habitat. The model starts at the mouth of a stream and iterates through each vertex of the stream flow line, calculating the gradient between the given vertex and the next vertex at least 100m upstream. It delineates additional stream segments at locations where the gradient exceeded the defined thresholds. Following delineation, the average gradient of each stream layer segment located within potential fish habitat was calculated with results classified according to the channel type categories. Finally, for potential habitat upstream of each crossing, stream lengths were summed within the average gradient categories with total areas of wetland and lake habitat also calculated.

Table 4. Stream gradient threshold and average gradient categories generated from the Fish Habitat Model and associated channel type.

*Gradient Range Channel Type 0 – 5% Riffle and cascade pool 6 – 13% Step pool 14 – 20% Step pool - very steep >20% Non fish habitat *Rounded to the nearest percent

Gradient threshold and average gradient categories were rounded to the nearest percent. Segments downstream of sections up to 13% grade were delineated and classified according to channel type groupings adapted from the British Columbia Channel Assessment Procedure Guidebook which include riffle and cascade pool and step-pool (FPC 1996, Table 4). Stream segments with sections containing gradients from 14 – 20% were classified as step pool - very steep. Stream segments upstream of 100 m sections with an average gradient >20% were considered non fish habitat. Although fish have been reported to utilize habitat with gradients up to 30% (Baxter 1999), a cutoff of 20% was used as the goal was to identify and prioritize crossing rehabilitation opportunities. Stream segments with gradients between 20-30% are extremely steep and do not typically provide high value spawning or rearing habitat.

6 RESULTS In the Bridge-Seton Rivers watersheds, 72 crossing structure assessments are catalogued within the PSCIS database (Table 5). Of these, 58 crossings are located on modelled fish habitat. For these crossings, 27 are documented as barriers and 5 are assessed as potential barriers and 26 are considered passable. Maps are provided as Attachment 1.

A detailed review and prioritization ranking was conducted for the 15 crossings structures identified as requiring further assessment according to the criteria identified in the methodology (Table 6). Of these, seven crossings were rated as high priority for follow up with habitat confirmation assessments and potentially fish inventories (Table 6, Table 9). Four crossings were rated as moderate priority for follow up with habitat confirmation assessments and potentially fish inventories (Table 6, Table 10). One crossing was rated as low priority for follow up with habitat confirmation assessments and potentially fish inventories (Table 6, Appendix 1). Available links to photos stored in the PSCIS database are provided in the “Stream” column of priority tables. Of note, site plans have been drafted for rehabilitation of PSCIS crossings 531, 540, 196501 over Quartz Creek and tributary with details provided within the PSCIS database. Details of these crossings are included in Table 9 and the crossings are highlighted as high priorities on Attachment 1 maps, however further ground surveys may not be required.

Forsite (2008), reports that some modelled crossings located on Cadwallader Creek and north of Liza Lake upstream of barriers should not be inventoried as these areas are non-fish bearing. A key to the data included in the digital file is detailed in Appendix 4.

To date Phase 1 - Fish Passage Assessments within the PSCIS database appear to have been conducted throughout most of the major potential fish bearing areas of the Bridge River watershed. However a substantial number of modelled crossings do not have associated PSCIS inventory data (Table 7). Fish passage culvert inspections were conducted in the Bridge Creek watershed for Ainsworth Lumber Company Ltd. in 1999 but this data is not accessible within the PSCIS database (Inland 2000). Ainsworth Lumber may have the digital record for the surveys which could prove useful for planning and coordination of future fish passage assessment in the watershed. Currently there is no data from stream crossing inventories in the Seton River watershed located within the PSCIS database with 271 crossings modelled as on habitat that is either confirmed fish bearing or suspected fish bearing (Table 8).

7 DISCUSSION AND CONCLUSION Previously identified crossings that are barriers to fish passage in the Bridge-Seton River watersheds were prioritized based on past assessment information, available fisheries data as well as estimated upstream habitat quality and quantity. The results provide a planning tool to help guide further assessment and restoration of crossings. It should be noted that the methodology used for this analysis is one of many possible approaches that incorporates assumptions about the value of fish habitat based on limited data, inferred quantities as well as somewhat subjective interpretations of habitat quality.

A detailed review and prioritization ranking was conducted for 15 crossings structures identified as requiring further assessment according to the criteria identified in the methodology. Of these, ten crossings were rated as high priority for follow up with habitat confirmation assessments and potentially fish inventories. Four crossings were rated as moderate priority for follow up with habitat confirmation assessments and potentially fish inventories and one crossing was rated as low priority for follow up. Of note, site plans have been drafted for rehabilitation of three of the high priority crossings (531, 540, 19650) over Quartz Creek and tributary with details provided within the PSCIS database. Details of these crossings are included in Table 9 and the crossings occur on Attachment 1 maps, however further ground surveys may not be required.

To date Phase 1 - Fish Passage Assessments within the PSCIS database appear to have been conducted throughout most of the major potential fish bearing areas of the Bridge River watershed. However a substantial number of modelled crossings do not have associated inventory data. Fish passage culvert inspections were conducted in the Bridge Creek watershed for Ainsworth Lumber Company Ltd. in 1999 but this data does not appear to be accessible within the PSCIS database (Inland 2000). Ainsworth Lumber may have the digital record for the surveys which could prove useful for planning and coordination of future fish passage assessment in the watershed. Currently there is no data from stream crossing inventories in the Seton River watershed located within the PSCIS database.

Within the Bridge River watershed 668 of the crossings not associated with PSCIS crossings are modelled as on observed or potentially fish bearing habitat. Within the Seton River watershed 271 crossings are modelled as on observed or potentially fish bearing habitat (Table 8). Forsite (2008), reports that some modelled crossings located on Cadwallader Creek and north of Liza Lake upstream of barriers should not be inventoried as these areas are non-fish bearing.

Assessment of crossing locations on modelled fish habitat in the watersheds that do not have associated PSCIS data is recommended and should be conducted according to FPTWG protocols. The FPTWG has prepared on-line training resources, field work guidance, field assessment protocols and data forms to help guide the collection of data and submission of assessment deliverables.

Phase 2: Habitat confirmation checks conducted according to protocols developed by the FPTWG (MoE 2011) are recommended for the crossings rated as high priority through this work. Habitat confirmation checks gather detailed field and background data on habitat quality and quantity, fisheries values, land use issues and regional fisheries concerns. This information is then incorporated into a standardized reporting format to further refine priority rankings and focus design (Phase 3) and remediation (Phase 4) on fish passage restoration opportunities into areas of critical habitat for species of interest.
